Definitions

  • the quick coupling and quick release means comprise a plurality of locking segments that are circumferentially distributed in a plane perpendicular to the axis of said fitting parts and housed in a radially movable way in respective radial slots of a projecting axial portion of a first fitting part that, during the coupling step, is superimposable to a corresponding projecting axial portion of the second fitting part.
  • a revolving ring can be controlled to rotate around the projecting portion of the first fitting part in order to work on said locking segments so as to bias them into radial housings of said projecting portion of the second fitting part or to house them in their radial housings, respectively for the coupling and the uncoupling of said fitting parts.
  • a hydraulic cylinder reacting between said first fitting part and said revolving ring usually provides to the movement of the revolving ring.
  • the only possible inconvenience can consist in a difficulty in uncoupling theoretically determinable by the missed working of the cylinder for the movement of the revolving ring, for instance because of a formation of ice after a long period of permanence of the connector in open sea or as a result of transfer of oil products at very low temperature. In such case, in fact, the ring does not rotate and the connector does not open in order to release the two pipes.
  • Scope of the present invention is now to provide a quick-coupling and quick-release connector of the aforesaid type, that is capable to guarantee the maximum safety in uncoupling, when required.
  • such scope is attained by using two hydraulic cylinders (or equivalent means) for the movement of the revolving ring which are arranged substantially at 180° to each other in the rotation plane of the ring and reacting, each one, between a first lever fastened to one of the two fitting parts and a second lever fastened to the revolving ring, and by dividing said first lever into a radially more external part and a radially more internal part connected with each other by an articulation which is modifiable in order to be able to assume two different operating conditions, one for the complete mutual locking of the two parts of the first lever and the other one for the consent of the rotation of the radially more external part of the first lever in the direction of approach to the second lever.
  • FIG. 1 shows a connector according to the invention in coupling condition, as sectioned along its axis according to the line I-I of FIG. 2 ;
  • FIG. 2 shows the same connector in transversal section according to the line II-II of FIG. 1 ;
  • FIG. 3 shows the connector sectioned as in FIG. 1 in the course of an uncoupling movement
  • FIG. 4 shows the connector sectioned as in FIG. 1 at the end of an uncoupling movement
  • FIG. 5 shows the connector sectioned as in FIG. 1 , ready for a new coupling movement
  • FIG. 6 shows the connector sectioned as in FIG. 1 at the end of the coupling movement.
  • the connector shown in the drawings comprises ( FIG. 1 ) a first tubular fitting part 1 and a second tubular fitting part 2 , each one made up of a respective body portion 3 , 4 and of a respective projecting axial portion 5 , 6 .
  • the body portions 3 , 4 are destined to the fastening, by means of screws 7 , 8 , to respective pipings 9 , 10 to be coupled.
  • the projecting portions 5 , 6 are in turn insertable one into the other one in order to define a single cylindrical passage 11 for the flow of fluid from one piping to the other one.
  • An axially mobile ring 12 is housed in an axial front housing 13 of the projecting portion 6 of the fitting part 2 and is thrust by a spring 14 toward the facing projecting portion 5 of the fitting part 1 .
  • quick-coupling and quick release means 15 which include ( FIG. 2 ) a plurality of locking segments 16 circumferentially distributed in a plane perpendicular to the axis of the passage 11 and housed in radially movable way in respective radial slots 17 of the projecting portion 6 of the fitting part 2 .
  • a revolving ring 18 is arranged that can be controlled to rotate by one or by the other one of the two independent by operable hydraulic cylinders 19 , that are located in diametrically opposite positions in the rotation plane of the ring 18 and normally in contracted position.
  • Each one of the two cylinders 19 has its two ends respectively hinged in 20 and 21 in a first lever 22 integral with the projecting portion 6 of the second fitting part 2 and in a second lever 23 integral with the revolving ring 18 .
  • the first lever 22 is subdivided into two parts 24 and 25 , the first one radially more external and the second one radially more internal, that are connected with each other by a modifiable articulation 26 made up of a hingement pin 27 and by a removable gudgeon 28 that is insertable in lined up holes 29 and 30 of the two parts of lever 24 and 25 .
  • the presence of the gudgeon 28 determines the mutual locking of the aforesaid parts of lever, whereas the absence of gudgeon 28 allows the first part 24 of the lever 22 to rotate in the sense of approach to the second lever 23 (counter-clockwise sense in FIG. 2 ).
  • a shoulder 39 of the second part 25 of the lever 22 prevents instead the first part 24 of the same lever 22 to rotate in clockwise sense as regards the second part 25 .
  • the two cylinders 19 are provided with mouths 31 and 32 that are normally connected with a common hydraulic control system and also connectable with manual emergency pumps.
  • the internal wall of the revolving ring 18 co-operates with the external end of the segments 16 in order to push out the latter ones toward the axis of the cylindrical passage 11 and into radial seats obtained as a continuous round recess 33 in the external wall of the projecting portion 5 of the fitting part 1 .
  • some radial seats 34 are obtained that, when the ring 18 is rotated as compared with the position in FIG. 2 , are capable to house the segments 16 for their output from the annular recess 33 of the fitting part 1 ( FIGS. 4 and 5 ).
  • the segments 16 can therefore be forced by the co-operating chamfers 35 and 37 to slide radially into the slots 17 in order to exit from the annular recess 33 and to insert themselves into the radial recess 34 of the projecting portion 6 of the fitting part 2 ( FIG. 4 ).
  • the two fitting parts 1 and 2 can thus get apart from one another with consequent separation of the piping 3 and 4 .
